Dissociative attachment in HCl, DCl, and F2

Dissociative Attachment in Selected Monochloroalkanes

Dissociative electron attachment to DNA.

Electron-stimulated desorption of anions from thin films of linear and supercoiled DNA is investigated in the range 3-20 eV. Resonant structures are observed with maxima at 9.4+/-0.3, 9.2+/-0.3, and 9.2+/-0.3 eV, respectively, in the yield dependence of H-, O-, and OH- on the incident electron energy. Their formation is attributed to dissociative electron attachment.

Chemical reactivity of ultracold polar molecules: investigation of H + HCl and H + DCl collisions

Quantum scattering calculations are reported for the H + HCl(v, j = 0) and H + DCl(v, j = 0) collisions for vibrational levels v = 0− 2 of the diatoms. Calculations were performed for incident kinetic energies in the range 10 − 10 eV, for total angular momentum J = 0 and s-wave scattering in the entrance channel of the collisions. Cross sections and rate coefficients are characterized by resona...

Dissociative electron attachment to abasic DNA.

Thin films of the short single DNA strand, GCAT, in which one of the bases has been removed were bombarded with 3 to 15 eV electrons. The yield functions of the H(-), O(-) and OH(-) ions desorbed from these films exhibit a broad peak near 9 eV, which is attributed to dissociative electron attachment to the basic molecules. Whereas removal of any one of the bases considerably decreases N-glycosi...

A dissociative electron attachment cross-section estimator

Dissociative electron attachment (DEA) is the major process where molecules are destroyed in low-energy plasmas. DEA cross sections are therefore important for a whole variety of applications but are both hard to measure or compute accurately. A method for estimating DEA cross sections based a simple resonance plus survival model is presented. Test results are presented for DEA of molecular oxy...
